             Summary: "deflate" encoding issue : java.util.zip.ZipException: invalid stored block lengths
                 Key: HTTPCLIENT-1550
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1550
             Project: HttpComponents HttpClient
          Issue Type: Bug
    Affects Versions: 4.3.5
         Environment: Windows
            Reporter: Guillaume Serre
            Priority: Minor


When trying to GET any nzb files from http://nzb.nl with an httpclient request, a ZipException is raised.

{code:title=JunitTestFailing.java}
	@Test
	public void testDeflateIssueFailing() throws ClientProtocolException, IOException {
		HttpGet httpget = new HttpGet("http://nzbindex.nl/download/72441827/BackTrack5R3.Gnome.iSO.32bit-LiNUX-0171-bt5r2gis32.par2.nzb");
		HttpClient client = HttpClientBuilder.create().build();
		HttpResponse response = client.execute(httpget);
		HttpEntity entity = response.getEntity();
		byte[] data = EntityUtils.toByteArray( entity );
		Assert.assertEquals( data.length, 423548 );
	}

{code}

The complete stack trace I get is this:

{code}
java.util.zip.ZipException: invalid stored block lengths
	at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:164)
	at java.io.FilterInputStream.read(FilterInputStream.java:107)
	at org.apache.http.client.entity.DeflateInputStream.read(DeflateInputStream.java:144)
	at org.apache.http.client.entity.LazyDecompressingInputStream.read(LazyDecompressingInputStream.java:68)
	at org.apache.http.util.EntityUtils.toByteArray(EntityUtils.java:136)
	at hclient.HTTPClientTest.testDeflateIssueFailing(HTTPClientTest.java:39)
{code}

A workaround I found is to set the Accept-Encoding header to only accept gzip, as follows:

{code:title=JunitTestWorking.java}
	
	@Test
	public void testDeflateIssueWorking() throws ClientProtocolException, IOException {
		HttpGet httpget = new HttpGet("http://nzbindex.nl/download/72441827/BackTrack5R3.Gnome.iSO.32bit-LiNUX-0171-bt5r2gis32.par2.nzb");
		httpget.setHeader("Accept-Encoding", "gzip");
		HttpClient client = HttpClientBuilder.create().build();
		HttpResponse response = client.execute(httpget);
		HttpEntity entity = response.getEntity();
		byte[] data = EntityUtils.toByteArray( entity );
		Assert.assertEquals( data.length, 423548 );
	}
{code}

Thanks
